CONTRACT  NO.  90 
BOARD  OF  WATER  SUPPLY  CITY  OF  NEW  YORK 

This  contract  was  awarded  on  June  20,  1911,  and  excavation  commenced  June  21,  191  1. 

The  contract  is  for  the  construction  of  a  deep  pressure  tunnel  under  the  Hudson  River  from  Cornwall 
to  Storm  King,  N.  Y.,  a  distance  of  3,030  feet.  There  are  two  shafts,  one  on  either  side  of  the  River,  the 
east  shaft  being  1,132  feet  deep,  and  the  west  shaft  1,159  feet. 

The  excavation,  which  was  conducted  from  both  sides  of  the  river  towards  the  center,  was  not  begun  on 
the  east  side  until  October  13,  1911,  because  of  the  fear  of  a  possible  rush  of  water,  and  in  order  to  provide 
against  same  a  concrete  bulkhead,  14  feet  in  thickness,  with  a  cast  steel  door,  was  installed. 

Between  the  bulkhead  and  shaft  were  erected  two  (2)  Worthington,  8-stage,  500-gallon,  centrifugal 
pumps,  operated  by  250  H.  P.  General  Electric  motors,  water  cooled,  and  of  submergible  type,  which  pumps 
would  discharge  water  to  the  surface  in  one  lift. 

In  addition  to  these  were  installed  two  (2)  Jeanesville  pumps,  Hazleton  pattern,  with  a  capacity  of  400 
gallons  per  minute  for  a  400-foot  head,  and  one  i  1  I  Cameron  pump  of  the  same  capacity  and  lift.  Water 
n  these  pumps  being  discharged  into  two  (2)  consecutive  lodgments  driven  off  the  shaft,  and  in  each  o\ 
installed  three    3    Jeanesville  pumps  of  same  type  and  capacity  as  above.    Total  capacity  of 
plant  discharging  to  surface  was  2,200  gallons  per  minute. 

'.ii  exai  i  duplii  ate  of  the  pumping  plant  described  above  was  installed  on  the  west  side  of  this  contract.

CONTRACT  No.  1 2 
RONDOUT  SIPHON,  BOARD  OF  WATER  SUPPLY,  CITY  OF  NEW  YORK 

\X  ork  on  this  contract  was  begun  in  June,  1908,  and  the  entire  contract  will  be  completed  early  in  1912. 

The  work  consists  of  eight  shafts  varying  in  depth  from  375  feet  to  710  feet,  a  concrete  lined  pressure 
tunnel  14'  _>  feet  finished  diameter,  and  4  'j  miles  long,  together  with  a  concrete  lined  tunnel  on  the  hydraulic 
gradient.  17  feet  high.  13  feet  4  inches  wide,  3,340  feet  long,  and  two  short  stretches  of  concrete  conduit. 

Shaft  No.  4  on  this  contract,  which  is  498  feet  deep,  was  sunk  with  great  difficulty,  owing  to  the  pres- 
ence of  large  quantities  of  sulphur  water,  which  was  encountered  first  at  a  depth  of  200  feet.  At  a  depth  of 
260  feet  the  flow  was  900  gallons  per  minute,  practically  all  of  which  was  sulphur  water.  In  the  excavation 
of  the  tunnel  from  the  foot  of  the  shaft  as  high  as  2,000  gallons  per  minute  had  to  be  taken  care  of  at  a  pres- 
sure of  95  pounds  per  square  inch.  In  fact,  the  average  amount  of  water  for  two  years  at  this  point  in  the 
tunnel  was  1,500  gallons  per  minute,  and  the  sulphur  contents  made  it  very  difficult  to  get  men  to  do  the 
work. 

A  pumping  plant  was  installed  near  the  foot  of  the  shaft  consisting  of  three  6-inch,  6-stage,  600-gallon 
V\  orthington  centrifugal  pumps,  operated  by  General  Electric  motors,  and  Cameron  horizontal  pumps,  oper- 
ated by  steam  and  compressed  air,  and  having  a  total  capacity  of  5,200  gallons  per  minute,  discharged  at  the 

top  of  the  shaft. 

An  emergency  water  lock  of  concrete,  with  a  very  heavy  timber  door  was  also  installed  in  the  tunnel 
between  the  pumping  plant  and  the  main  inflow  of  water. 

November  30,  1910,  this  lock  was  brought  into  service  due  to  a  surface  explosion,  which  cut  off  the 
power  to  the  entire  pumping  plant  for  a  short  time.    When  pumping  operations  were  again  resumed,  a  dis- 
rge  to  the  surface  of  4,800  gallons  per  minute  was  maintained  until  the  heading  was  unwatered  and  the 

normal  flow  again  encountered. 

The  principal  construction  quantities  were  as  follows: 

Shaft  Excavation   45,000  cubic  yards 

Tunnel  Excavation   300,000  cubic  yards 

Concrete  in  Shafts  and  Tunnels   140,000  cubic  yards 

Portland  Cement   235,000  barrels

POWER  PLANT  FOR  THE 
ST.  LAWRENCE  RIVER  POWER  COMPANY 

The  main  Power  Plant  was  built  under  a  contract  made  in  1898,  and  called  for  the  construction  of  a 
canal  from  the  St.  Lawrence  River  to  the  Grasse  River;  of  a  power  house  with  its  foundations,  forebay 
and  tail  race;  of  all  highways  and  bridges  made  necessary  by  reason  of  the  canal;  and  for  the  construction 
of  a  railroad  from  Massena  Springs  to  the  Power  House,  a  distance  of  about  3  miles,  in  which  are  two 
steel  bridges,  viz.,  one  across  the  Racquette  and  one  across  the  Grasse  River. 

The  construction  quantities  included  6,000,000  cubic  yards  of  Excavation;  35,000  cubic  yards  of  Con- 
crete. 

This  contract  was  completed  in  1902. 

May  28,  1910,  an  additional  contract  was  entered  into  for  the  construction  of  an  Ice  Sluice  and 
Dam  adjoining  the  Power  House  of  the  St.  Lawrence  River  Power  Company. 
This  work  was  completed  in  the  Spring  of  191  I.
